To explain all this, to classify it scientifically and to arrange it serially, would be, nowadays at least, an unscientific enterprise. These phenomena pass from body to body and are as reliable as inexplicable. Who has never observed them, and although his attention has been called to them, still has failed to notice them, need not consider them, but persons believing in them must be warned against exaggeration and haste. The one advice that can be given is to study the language of the hand before officially ignoring it; not to decide immediately upon the value of the observations one is supposed to have made, but to handle them cautiously and to test them with later experiences. It is of especial interest to trace the movement of the hand, especially the fingers. I do not mean those movements which are external, and co-ordinate with the movements of the arm; those belong to mimicry. I mean those that begin at the wrist and therefore occur in the hand only. For the study of those movements the hand of childhood is of little use, being altogether too untrained, unskilled, and neutral. It shows most clearly the movement of the desire to possess, of catching hold and drawing toward oneself, generally toward the mouth, as does the suckling child its mother’s breast. This movement, Darwin has observed even among kittens. The masculine hand is generally too heavy and slow, clearly to exhibit the more refined movements; these are fully developed only in the feminine, particularly in the hands of vivacious, nervous, and spiritually excitable women. The justice who observes them may read more than he can in their owner’s words. The hand lies in the lap apparently inert, but the otherwise well concealed anger slowly makes a fist of it, or the fingers bend characteristically forward as if they wished to scratch somebody’s eyes out. Or they cramp together in deep pain, or the balls of the four other fingers pass with pleasure over the ball of the thumb, or they move spasmodically, nervously, impatiently and fearfully, or they open and close with characteristic enjoyment like the paws of cats when the latter feel quite spry.
